AUTOMATIC CUT-OUT FOR SWITCHES.

Specification of Letters Patent.

Patented Oct. 2, 1917.

Application filed January 29, 1916. Serial No. 74,997.

To all whom it may concern;

Be it known that I, ALFRED B. THE.- LIlSOI-I, a subject of the Emperor of Germany, residing at 17 34 Ballou street, in the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Automatic Cut- Outs for Switches, of which the following I then automatically reset itself, and to so construct and arrange the parts that the switch pole may be manually swung into and out of circuit closing position without disturbing the out out mechanism.

These and other objects I accomplish as set forth in the following specification and as particularly pointed out in the appended claim, reference being had to the accompanying drawings in which an embodiment of my invention is shown.

In the drawings 4 Figure 1, represents a front elevation of a suitable support with that portion of the switch mechanism located on the front of the support shown in circuit closing position.

Fig. 2, is an edge or side elevation of the device.

Fig. 3, is a back or rear elevation of the device.

Fig. 4, is a transverse horizontal section through the device on line 4.4 of Fig. 3 and looking downward in the direction of the arrows in said Fig. 3.

Fig. 5, is an enlarged detail detached perspective of the pivoted catch attached to the switch pole.

In referring to the drawings in detail, like numerals indicate corresponding parts.

My improved mechanism is located on and attached to a suitable support such as the wooden board 1 shown, part of the mechanism being arranged on the front and part on the rear of the support.

In the embodiment of my invention shown in the accompanying drawings the switch pole comprises a series of three circuit closing arms 2, a transverse bar 8, from which said arms extend at intervals and a handle 4, projecting from the opposite side of the bar.

The outer extremity of each arm 2 is pivoted to a block 5 by a pivot pin 6, and said block is fastened to the front of the board 1, and carries one of the electric terminals 7.

Blocks 8 are also fastened to the board vertically above the blocks 5, and carry the opposite electric terminals 9.

The upper blocks are also provided with spring forked members 10, in which the arms 2 are forced when the switch pole is in circuit closing position, as shown in Figs. 1 and 4. The switch pole is normally locked in position by a catch and is adapted to be forced downward to break the circuit when the catch is released by a spring 11.

The catch is shown more particularly in Fig. 5, and consists of a plate 12, which is fastened to the transverse bar 3, and has two projecting cars 13, spaced apart from each other, a pivot pin 14, extending between said ears, a curved catch latch 15 pivotally mounted on said pin 14, and a coil spring 16, loosely fitted around the pin on one side of the latch and having an angular bent end 17 which fits over the side of the latch.

The opposite end of the spring 16, is secured in any desired manner to prevent rotation.

The tendency of the spring is to maintain the latch in looking position as shown in Fig. 2.

Upon the opposite side of the support I arrange a suitable electro-magnet 18, and in proximity to said magnet I place a trigger 19, which is pivoted at one end by a pivot 20 to an angular bracket 21 fastened to the support.

A rock shaft 22, extends through the board, being journaled in a bearing 28, and

one end of said shaft is bent at an angle to jecting end of the shaft, being secured thereto by a set screw 28.

The upper end of-thecrank arm 26 is adapted to be normally held by the trigger 19, as shown in Fig. 3.

A stop pin 29 extends from the bracket 21, for limiting the downward movement of the trigger and upon which said trigger rests when in supported position.

The crank arm 26, is stopped in its movement in a releasing direction by a vertical lug 30, and is brought back automatically to its normal'position after the switch pole is released by a comparatively weak spring 31, which is fastened at one end to an ear 32 on the plate 25, and at its oppositeend to a lateral ear 33,0n the crank arm.

The mechanism-herein described, I term an automatic cut-out as by energizing the electro-magnet, 18, the trigger 19 islifted from its horizontal locking position freeing the crank arm 26 and allowing the pull of the spring 11, exerted through the catch to rock the shaft 22, and depress the lateral supporting arm 24 sufiiciently to release the said catch,'thereby releasing the switch pole and permitting it to be automatically drawn downward by the tension of the spring 11, to a circuit breaking position.

After the switch pole is released the rock shaft 22, is turned in the opposite direction by the return spring 31, thus restoring the parts of the cut out mechanism to their locking position in readiness to again lock the switch pole in a circuit-closing position when it is returned tosuch position.

In this improved device the switch pole may be moved in either direction by han d without affecting the cut out mechanism,

which is an independent'mechanism which serves simply to release the switch pole automatically under' certain conditions.

\Vhile I have illustrated and described a preferred form of construction for carrying my invention into efi'ect this is capable of a wide range of variation, alteration, modification and change without diiparting from the spirit of my invention, therefore do not wish to be limited to the construction herein "shown and described, but desire to avail myself of all such variations, alterations, modifications and changes as fairly fall within the scope of the appended claim or may be construed to be within the scope thereof by involving the doctrine of equivalents.

This improved switch may be used in connection with a variety of different devices, such for instance as clocks.

What I claim as my invention and desire to secure by Letters Patent is In a device of the class described, the combination with a manually spring opened switch, of a spring ressed catch on said switch, trigger meclianism engaging the catch to hold the switch closed, means for tripping said mechanism torelease it to the action of the catch and a resilient member which automatically resets the trigger mechanism; said mechanism being independent of the switch and maintaining its set position when the switch is manually operated.

Chicago, Illinois, January 26th, A. D. 1916.

In testimony whereof I have hereunto set my hand.
